machine adapted to display a seriesofcards successively, the cards being kept in a compartment where all are concealed exceptthe one immediately 1n view.

" An object of the invention is toproduce a machine which will becompact, and which will be capable of displaying. a largenumber of cards or a small number of: cards one at a time as may be desired.

Other objects of theinvention will appear as. the description proceeds.

An embodiment of the invention is shown in the drawing in which the same reference numeral is appliedto the same portion throughout, but I am aware that there may be many. modificationsthereof,

Figure 1 is a perspective V ew of thecom plete machine showing oneeard in position to be viewed. 7

Fig. 2 is anend view of the mechanism for operating the card lifting. arms.

Fig. 3 is a sideelevation partlyin section of the mechanism for operating the card lifting arms, and- Fig. 4 is a View of themechanism for operating the card lifting arms obser ed, from Fi 5 isv a side eleva I H of the casing cut away, for the purpose of illustration of the entire display apparatus,

showing. the display armsin position to pick up a fresh card.

The numeral 1 indicates a suitable; chest or casing within which the operating mechanism is placed, the top v of the, casing having three easellegs Q, 421ml 5, connected together at the top with a cross piece 6 andv held in a fixed position by means of the brace .7.- The cross'piece. 6' has; twob ackwardly projecting arms 8 and 9, which are for thepurpose ofreleasingthe, cards in. a. manner to be presently explained. Mounted in the box is a shaft 10, which carries two arms 11 and 12, which arms have hooks at their upper ends, as indicated at 13, to engage openings in the edge of the cards.

The cards areheld engaged with the hooks 13 by means of the two lugs 14 and 15 one for each arm, and when it is necessary to release the cards theyarereleased by aslight' upward movement of the arms 11 and 12,. which brings the lower ends of the lugs 14 and 15 into engagement with the arms 8, and, 9 thereby dropping the card. The shaft 10 has an arm 17 connected therewith, which arm is in turn connected by means of a short link 18 and long link 19 with the pin 20 01, a rotating arm 21, the latter arm being. loosely mounted on the shaft The open-j ating mechanism just referred tois allsupported by means of a standard 23', within the chest 1, and which has bearings 24, 25; and 26 vfor the shafts 22, shaft 22. has a flange 29, to which theworm wheel 30 and a disk 31 are bolted. Thedisk 31 has a notch 32 for the purpose presently to be; explained. The shaft 22 is also provided with a very small spur gear'33which gear is in mesh with a larger spur gear 34 on the shaft 27 The gear 34 has a pin? so positioned as to engage an arm 3'6 on t-h e;

shaft 28, the object being to raise the latch 37 also on the shaft 28 to allow the pawl 39 to engage the detent or notch 32; a spring: 40 holds the latch 37 normally down, and it has a projecting lug 41, which bears upon a pin 42 to hold said latch'out of engagement with the notch 32 as wellas a hook" at 43 which engages a point 44 on the end of the lever 21, the object being to prevent the lever from passing a fixed point and thereby dropping the card being displayed; The, operation of the apparatusis as follows-:

Assuming the motor H to drive the shaft;

45 and wormgear46, it will be. seen that the worm wheel 30 will be continuouslyrotated and'as. it is continuously rotated, it rotates the disk 31. At the same time, the shaft 22 will rotatethe smallgear 33: and; thelarge gear 34, and each time the large gear rotates, its pin135- will. contact;- with.

upon the card is dropped off the hooks 13. Continuing the movement, the arms 11 move down until they assume the position shown in Fig. 5, whereupon they will take up another card, and as the movement continues they will lift the card from the front of the pile until the lugs 14, 15 drop behind it and firmly hold it in place. 7

When the arms reach the position shown in Fig. 1, they will stop because the end of the lever 39 strikes the end of the lever 37 and causes it to be disengaged from the detent 32 of the disk 31. As soon as the levers 37 and 39 assume the relative position. shown in Fig. 4, the lever 21 will be pre vented from turning backward by the hook 43 and the pin 42 will :revent the lever 89 from being reengaged with the detent 32 until the pin 35 again operates the lever 36.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows 1. An advertising machine comprising a display rack, a card receptacle, means to lift the cards one at a time out of the receptacle to a position upon the display rack, and fixed stops against which the card lifting means is pressed to release the cards to allow them to be returned to their receptacle after hav ing been displayed for a period of time, the operation of the apparatus being adapted to be carried on indefinitely as described.

2. An advertising machine comprising a display rack, a receptacle for a series of cards, means to remove the cards from the front of the receptacle and display them upon the rack, and fixed stops against which the card lifting means is pressed to release the cards after having been displayed so that they will be returned to their receptacle at the back of the series of cards therein.

3. An advertising machine comprising a display rack, a card receptacle, means to hold a series of cards therein adjacent the front of the receptacle, means to pick up said cards, one at a time, from the front of the series of cards in said receptacle and display them upon said rack, fixed stops against which the card lifting means is pressed to release the cards after having been displayed so that they will fall into receptacle therefor at the back of the series of cards therein.

4. Amechanical movement for advertising machines comprising card display apparatus, including an oscillating shaft, a revoluble shaft, a lever loosely mounted thereon connecting with the oscillating shaft, a pawl pivotally connected to the loosely Copies of this patent may be obtained for mounted lever, a revoluble notched disk, means to hold said pawl out ofengagement with said disk, and means to intermittently allow said pawl to engage said disk to display a fresh card.

5. A mechanical movement for card display machines comprising a shaft, card carrying arms thereon, an arm on the shaft for oscillating it, a link connected with the arm, a revoluble shaft, a notched disk thereon, an arm loosely mounted on the latter shaft, a pawl carried thereby, and means to periodically cause the pawl to engage the notched disk to intermittently oscillate the first shaft.

6. A mechanical movement for display machines comprising a card display appa ratus, a shaft for operating said'apparatus, a revoluble notched disk, a pawl adapted to take in the notch-of said disk, a revoluble arm carrying said. pawl for operating the display apparatus, a latch for holding the pawl out of engagement with said notch and for holding the arm, and a slow. moving wheel carrying means for releasing the latch once in every revolution thereof.

7. A mechanical movement for display machines comprising a card display apparatus, a shaft for operating said apparatus, a revoluble notched disk, an arm loosely mounted upon the shaft carrying said notched disk, a pawl carried by said arm and adapted to take in the notch in said disk, a latch to hold said pawl out'of engagement with said notch and for holding the arm and a slow moving wheel having a lug adapted to release said latch once during each revolution thereof, the arm being caused to complete one entire movement during a fraction of the time the wheel with the lug thereon turns once.

8. A mechanical movement for display machines comprising a revoluble notched disk, a shaft upon which said disk is mounted, an arm loosely mounted upon the shaft carrying said disk, a pawl on the arm adapted to take in the notch in said disk, a'latch for holding the pawl out of engagement with the notch in said disk, and for holding the arm, a small gear on said shaft, a larger gear in mesh therewith, carrying means to release the pawl on each revolution thereof, and display apparatus connected with the arm.

In testimony whereof I have hereunto set my hand this 23d d y of November, A. D. 1916.
